An overload prevention device has a first rotational member for driving engagement with an input shaft of an auger transmission of a snow removing machine, a second rotational member engaging the first rotational member for rotation therewith over a predetermined torque range and for rotation relative thereto when a predetermined torque is exceeded, and a movable member mounted adjacent to the first rotational member for undergoing movement to restrict a rotating angle of the second rotational member. A detector outputs a detection signal each time the detector detects movement of the movable member in a direction away from the first rotational member when protuberances of the movable member engage protrusions of the first rotational member responsive to relative rotation between the first and second rotational members. A control unit stops operation of the engine when the detector outputs the detection signal a preselected number of times within a preselected time period.

A self-propelled walk-behind snowplow vehicle has a vehicle body and a vertical engine mounted on an upper part of the vehicle body. The vertical engine has a crankshaft disposed generally vertical and a cylinder head disposed generally horizontal to a longitudinal direction of the snowplow vehicle. The cylinder head projects from the vehicle body in a rearward direction of the snowplow vehicle. Left and right traveling units are mounted on a lower part of the vehicle body at left and right sides thereof. A muffler is connected to the engine and is disposed below the engine and located between the left and right traveling units. The vehicle body and the left and right traveling units together define a downward opening space within which the muffler is disposed.

A locking device for a parking brake is provided which ensures that the operation of locking a parking brake lever and the operation of releasing the locking of the parking brake lever can be carried out in a single stage. The parking brake lever is pivotally supported on a mounting bracket mounted on a steering handle by a first support shaft, and a lever locking member is pivotally supported on the mounting bracket by a second support shaft, and biased by a torsion spring. When the parking brake lever is operated, an engage groove in the parking brake lever is brought into engagement with a locking pin, whereby the parking brake lever is locked at a brake operating position. When an operating portion of the lever locking member is urged in a direction against a resilient force of the torsion spring, the engagement of the engage groove and the locking pin with each other is released, whereby the parking brake lever is pulled by a Bowden cable and swung back to an original brake releasing position.
